IPC: H03K19/00
Filed: 1982-11-24
Abstract: PURPOSE:To reduce the power consumption by providing an MOSFET operated by a clock in series with a pull-up resistor provided with a CMOS input circuit. CONSTITUTION:An input signal applied to an input terminal 7 is applied to a CMOS circuit comprising MOSFETs1, 2 and its output is fetched to the inside through a transmission circuit 6. A timing circuit 5 forms a signal input timing clock 400 from a signal input instruction 500 and an input timing clock 600, applies the clock 400 to the transmission circuit 6 and controls the operation. For example, a key swtich is connected between an input terminal 7 and a ground level and a current flows through a pull-up resistor 3 at all times. The MOSFET4 is connected in series with the resistor 3 to prevent the current from flowing, the signal input timing clock 400 is applied to the gate and the resistor 3 is connected only when the input signal is fetched.

Title: Supercharged internal combustion engine
Inventor: OZEKI TAKASHI
IPC: F02M29/06
Filed: 1985-09-18
Abstract: PURPOSE:To reduce an oil supply and an oil consumption as well as to prevent white smoke from occurring, by forming a suction passage in and around a combustion chamber into a spiral form, while installing an oil receiving recessed part in a lower part of the downstream end side, and interconnecting this recessed part to the suction passage at the upstream side of a crankcase through an interconnecting passage. CONSTITUTION:A pressurized air-fuel mixture inside a chamber 18 is fed to the inside of a combustion chamber 19 through a spiral suction passage 2a. At this time, the air-fuel mixture forms a spiral by a helical plate 20 and a spiral vortex is produced there. And, with centrifugal separating action following this vortex, lubricating oil in the mixture is separated and collected in an oil receiving recessed part 21. Then, the lubricating oil is fed to the inside of a suction pipe 14 at the upstream side of a crankcase 5 through an interconnecting passage 22, and again mixed in the mixture. At this juncture, when a lubricating oil quantity in the recessed part 21 is little due to a float check ball 23, this interconnecting passage is closed. Therefore, an oil supply and an oil consumption are reducible, while such an air-fuel mixture as being high in lubricating oil content is by no means entered into the combustion chamber 19 so that white smoke is prevented from occurring.

Title: Magnetic impedance sensor circuit
Inventor: NAKAGAKI TOSHIYA
IPC: G01R33/02
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To reduce the temperature drift of a magnetic impedance element and its drive/detection circuit by applying a bias magnetic field in an opposite direction to each of two magnetic impedance elements. SOLUTION: A high-frequency current is supplied from a bi-phase high-frequency oscillator 5 to magnetic impedance elements 1a and 1b, and a bias magnetic field is applied by bias coil winding 2a and 2b. When an external magnetic field Hex is applied to the magnetic impedance elements 1a and 1b in this state, the impedance of the magnetic impedance elements 1a and 1b is changed and an operation point is changed. Since a bias magnetic field in an opposite direction is being applied to the magnetic impedance elements 1a and 1b, the traveling direction of the operation point faces backward, and the external magnetic field Hex can be detected as the difference.  More specifically, the amplitude value of the magnetic impedance elements 1a and 1b is subjected to synchronous detection by a detection circuit 7 and is smoothed by a DC amplifier 8, thus converting the external magnetic field Hex to a DC voltage value.
